Nthawi zambiri, mabanja ambiri amasankha tebulo lolimba lamatabwa. Inde, anthu ena amasankha tebulo la nsangalabwi, chifukwa mawonekedwe a tebulo la nsangalabwi ndi apamwamba kwambiri. Ngakhale kuti ndi yosavuta komanso yokongola, imakhala ndi kalembedwe kabwino kwambiri, ndipo mawonekedwe ake ndi omveka bwino, ndipo kukhudza kumakhala kwatsopano. Ndi mtundu wa tebulo womwe anthu ambiri angasankhe. Komabe, anthu ambiri sadziwa zinthu za tebulo la marble, ndipo amasokonezeka akasankha.

Kuchokera pazamalonda, miyala yonse yopangidwa mwachilengedwe ndi yopukutidwa imatchedwa marbles. Si miyala ya nsangalabwi zonse yomwe ili yoyenera pamisonkhano yonse yomanga, motero miyala ya nsangalabwi iyenera kugawidwa m’magulu anayi: A, B, C ndi D. Njira yogaŵira iyi ndi yoyenera makamaka mwamwala wosalimba wa kalasi C ndi D, womwe umafunika kusamalidwa mwapadera usanakhazikitsidwe kapena poika. .

Pali mitundu inayi ya nsangalabwi

Kalasi A: nsangalabwi yapamwamba kwambiri, yofanana, yokonzedwa bwino kwambiri, yopanda zinyalala ndi pores.

Kalasi B: ndi ofanana ndi nsangalabwi wakale, koma kachitidwe kake kamakhala koyipa pang'ono kuposa wakale; ili ndi zolakwika zachilengedwe; imafunika kupatukana pang'ono, kumata ndi kudzaza.

Kalasi C: pali kusiyana mu processing khalidwe; zilema, pores ndi kapangidwe fractures zambiri. Kuvuta kukonzanso kusiyana kumeneku ndi kwapakati, komwe kungathe kuzindikiridwa ndi njira imodzi kapena zingapo zolekanitsa, gluing, kudzaza kapena kulimbikitsa.

Kalasi D: imakhala yofanana ndi miyala ya marble ya kalasi C, koma imakhala ndi zolakwika zambiri zachilengedwe, zomwe zimakhala ndi kusiyana kwakukulu pakukonzekera, zomwe zimafuna chithandizo chambiri chapamwamba ndi njira yomweyo. Mtundu uwu wa marble uli ndi miyala yambiri yokongola, imakhala ndi mtengo wokongoletsera wabwino.

Mitundu ya tebulo la marble

Gome la nsangalabwi lagawidwa kukhala tebulo lopanga la nsangalabwi ndi tebulo lachilengedwe la nsangalabwi. Mitundu iwiri ya mabulosi ndi yosiyana kwambiri. Kachulukidwe ka tebulo la marble lochita kupanga ndilokwera kwambiri, ndipo banga lamafuta silikhala losavuta kulowa, kotero ndi losavuta kuyeretsa; pamene tebulo lachilengedwe la marble ndilosavuta kulowa mkati mwa mafuta chifukwa cha mizere yachilengedwe.

Gome la nsangalabwi zachilengedwe

Ubwino: mawonekedwe okongola komanso achilengedwe, kumva bwino kwa dzanja pambuyo pa kupukuta, mawonekedwe olimba, kukana kuvala bwino poyerekeza ndi mwala wochita kupanga, osawopa utoto.

Zoipa: nsangalabwi zachilengedwe zimakhala ndi danga, zosavuta kuunjikira dothi lamafuta, mabakiteriya oswana, ndi nsangalabwi ali ndi pores zachilengedwe, zosavuta kulowa. Ena mwa iwo ali ndi cheza, ndipo kusalala kwa nsangalabwi zachilengedwe ndi osauka. Pamene kutentha kumasintha mofulumira, kumakhala kosavuta kusweka, ndipo kugwirizana pakati pa marble kumakhala koonekeratu, kotero kusakanikirana kosasunthika sikungatheke. Komanso, elasticity yake sikokwanira, choncho n'zovuta kukonza.

Tebulo la nsangalabwi

Ubwino: mitundu yosiyanasiyana, kusinthasintha kwabwino, palibe chithandizo chodziwikiratu cholumikizira, malingaliro amphamvu onse, ndi zokongola, zowala za ceramic, kuuma kwakukulu, kosavuta kuwononga, kukana dzimbiri, kukana kutentha kwambiri, komanso kosavuta kuyeretsa. Mwala wochita kupanga wa simenti, marble wochita kupanga wa poliyesitala, mwala wophatikizika wamtundu wochita kupanga ndi mtundu wa sintering marble wochita kupanga ndi mitundu inayi ya nsangalabwi yodziwika yodziwika pakali pano.

Zoipa: gawo lopangira mankhwala limavulaza thupi la munthu, kuuma kwake kuli kochepa, ndipo kumawopa kukanda, scalding ndi utoto.

Gome la nsangalabwi lili ndi zabwino zinayi

Choyamba, pamwamba pa gome lodyera la nsangalabwi sikophweka kuipitsidwa ndi fumbi ndi zokopa, ndipo mawonekedwe ake akuthupi ndi okhazikika;

Chachiwiri, tebulo lodyera la marble limakhalanso ndi ubwino kuti mitundu yonse ya matebulo odyetsera a matabwa ndi osayerekezeka, ndiko kuti, tebulo lodyera la marble silimawopa chinyezi ndipo silimakhudzidwa ndi chinyezi;

Chachitatu, nsangalabwi ali ndi makhalidwe osapindika ndi kuuma kwakukulu, kotero tebulo lodyera la nsangalabwi limakhalanso ndi ubwino uwu, komanso limakhala ndi kukana kwamphamvu kuvala;

Chachinayi, tebulo lodyera la nsangalabwi lili ndi mphamvu zotsutsa asidi ndi zowonongeka za alkali, ndipo sipadzakhalanso nkhawa ndi dzimbiri lachitsulo, ndipo kukonza kumakhala kosavuta, moyo wautali wautumiki.

Zolakwika zinayi za tebulo la marble

Choyamba, tebulo lodyera la marble ndi lapamwamba kwambiri, lomwe ladziwika ndi ogula. Komabe, chitetezo cha thanzi ndi chilengedwe cha tebulo lodyera la marble sichiri chabwino monga cha tebulo lodyera la nkhuni zolimba;

Chachiwiri, zikhoza kuwoneka kuchokera pamwamba pa kabati ya marble kuti pamwamba pa marble ndi yosalala kwambiri, ndipo chifukwa chake ndizovuta kupukuta pamwamba pa tebulo la marble ndi mafuta ndi madzi nthawi yomweyo. M'kupita kwanthawi, pamwamba pa tebulo likhoza kupakidwanso ndi varnish;

Chachitatu, tebulo lodyera la nsangalabwi nthawi zambiri limakhala lamlengalenga, lokhala ndi mawonekedwe, kotero zimakhala zovuta kuti zigwirizane ndi banja laling'ono lamtundu wamba bwino, koma ndilabwino kwambiri pakugwiritsa ntchito banja lalikulu, chifukwa chake pali kusowa kosinthika;

Chachinayi, tebulo lodyera la marble silili lalikulu kokha m'derali, komanso ndi lalikulu komanso lovuta kusuntha.

Pomaliza, Xiaobian akuyenera kukukumbutsani kuti ngakhale mukudziwa chidziwitso cha tebulo lodyera la marble, mutha kubweretsanso katswiri kuti akuthandizeni kugula tebulo lodyera la nsangalabwi, lomwe ndi lotetezeka kuti musasokonezedwe ndi zolankhula za anthu.
